Application-filed Iehruary 14,1911. Serial 1103508,!528551? i 'Be it known that I, FREDER'IOK'P. RENNE- BURG, a citizen of the United States,'r esidin at Baltimore, in the "State of Marylan have invented certain new and useful Improvements in Presses, of which the followin is-a specification.

This invention relates to improvements in'presses and has particular reference to devices of this character employed in extracting the oil from 'fish.

The invention consists in the improved construction, combination and arrangement of parts hereinafter setforth and particu- 'larly pointed out in the claims.

. The invention is illustrated in the accom- -n in drawings, wherein, Fi gfie 1, shows the machine'in perspective. Fig. 2, is a top plan view of the feed-in end of the machine. Fig. 3., is a vertical longitudinal section through the larger feed-in end of the machine. Fig. 4, is a top plan view of the smaller dischargeend of the machine. I Fig. 5 is a vertical longitudinal section and, partly side elevation of the machine at the discharge end. Fig. 6, is a vertical cross-sectional elevation through the machine taken on the line 6-6 of Fig. 3 and looking toward the feed hop-.

per. Fig. 7, is an enlarged cross-sectional detail through the slatted upper cylinder member. Fig. .8, is a cross-sectional detail through one of the arch-shaped bars to which the cylinder slats are secured. Fig. 9, is a perspective detail of one of the slat-se curing bolts, and Figs. 10 and 11, areendviews and side elevation respectively of a pair of adjacent slats and the bolts that secure them together and to the arch-shaped bars.

Referring to the drawings, thenumeral, .1, designates two parallel side walls of the machine of structural steel which are connected by a bearing late, 2, at one end and a suitable bracket p ate, 3, at the opposite end, all forming a rectangular structure having sufiicient strength and rigidity for the use to which it is to be put. The said two walls, 1, have a straight bottom from one end to the other, but these walls at their ends are vertically higher than the part of the wall intermediate of said ends. This construction afiords useful results that will be presently descri d.

The bearin ate, 2, at the one end of the two side ls and the bracket plate, 3,

at theopp'osite end-are provided with bearlngs, 4, and 5, res ctively, which .sustain the opposite ends qoFii-screw-conveyer shaft, his eonveyer shaft hasaspirahthread,

7, :which'is larger atone-end than'th'e other and which is gradually reduced in diameter from-the larger to the smaller end. "Itm-ay be remarked that the shaft, 6,-and the spiral conveyer, 7, constitute one integral metal structure, which part alone we'i be six thousand pounds in a fish-press like that shown in the drawing. "In a" large and heat? machine of this character the shaft, 6, .o the heavy spiral "conveyermust have itsend bearings, 4, and, 5, sup orted'by a mass of metal that will afford 516 requisite stability and rigidity; for this reason I have contrived that the'ends of the side walls, '1, shall behigh enough to servethis'objectand at the same'time I havemadethe horizontal top edge of the side walls intermediate of the ends depressed or lower than the ends in order to avoid hindrance'to the outward side-swinging of the link-bars, 32', 1 presently to be described. The conveyer-shaftatthe larger :end is provided with a' hard metal plug, 8, against which the inner end of a thrust bolt, 9, impinges. The bolt :passes through a head, 10, fixed on the bearing plate, 2, and carriesra't-hreaded head, 11, at the inner side of the head, 10, and a locknut, 12, at the outer side of said'head whereby the longitudinal movement of the bolt will effect a corresponding adjustment of the conveyer, explained.

The spiral conveyor-is inclosed in a-slatted I shell of improved construction which will now be described. At interv-als between the ends the side walls, -1, sustain a series of lower semi-cylindric bracket supports, 13, each of which is of a different diameter than those at either side of it so that the supports will be 'fromthe receiving end where they are larger to the discharge end where they are smallest,'the upper edges, 14, however of all the lower supports are in the same horizontal plane. These bracket supports have flanges, 15, which seat against and are bolted to the side walls, 1, as may be read in Figs 1, 2 and 4 of the drawings. Each bracket support also has a flange, 16, at its inneredge for a purpose'to be explained.

In order'to form a slatted casing about the screw conveyor .I:provide a series of longitudinally extendingslats or-bars, 17, which,

. I 4 I it willbe noted by reference to Figs. 7,

and 11, are tapered in cross-section,-being wider at their inner faces, 18, than at their outer faces, 19. The slats or bars are arranged longitudinally and in pairs side-byside with the broader inner surfaces comaratively close together and thereby prouce a series of V-shaped or tapered longitudinal slots, 20. At intervals between their inner ends the slats or bars are secured together in pairs by means of bolts, 21, having tapered heads, 22, each with a perforation, 23, therein, as seen in Fig. 9. The tapered head of the bolt is inserted in the tapered longitudinal slot, 20, between the bars and a rivet or equivalent fastening 24, is passed crosswise through the bars and also throu h the perforation, 23, of the bolt head.. fiy

' this means the bolt heads, 22, serve to secure the slats together and also to hold them in a spaced-apart position. A nut, 25, is provlded on the outer end of each bolt, 21, and by reference to Fig. 8, it will be seen that one side of the nut will seat on the flange, 16, of the bracket support.

A semi-circular bar, 26, is placed around the outer side of the slats or bars and against the opposite side of the bolts, 21. The crosssectional areaof the bar being such that its outer curved surface will be parallel and flush with the flange, 16, of the bracket support and thereby the bolts, 21, have position in a slot formed between the said flange, 16,

and the semi-circular bar, 26. By means of this construction the outer side of the nut, 25, will seat on the bar, 26, while the inner side of said nut will seat on the flange, 16, consequently the slats or bars, 17, will be drawn outward and held against the arched or curved faces of the bracket supports. In

order toprevent displacement of the bar, 26,

I provide a clip bar, 27 which has its opposite ends, 28, turned outwardly, as clearly seen in Figs. 7 and 8. This clip bar seats on the longitudinal slot, 20, between the slats and extends across the inner surface of the bracket supports, and one out-turned end projects at the outer side of the bar, 26, while the other out-turned end projects behind the wall of the rigid bracket support. By this means the bar, 26, cannot move laterally and away from the support and the bolt head, 25, is sustained at opposite sides.

In practice I have found it advantageous to form the slatted shell in two longitudinal sections, an upper and a lower section, and consequently the slats or bars extend only from one end to the other of the articular section of which it is a part. In the resent instance the machine 1s shown as aving three sections, 29, 30, and, 31, respectively, the section, 29, being the largest and the section, 31, the smallest. When the slats or bars have been secured to the series of lower supports, 13, they will form the lower half mutate of the slatted shell on which the upper half- I of the shell will be placed. 7 Each lower sup"- ort, 13, is provided with abifurcated link ar, 32, which straddles the support and has its lower end pivotally connected theretob means of a pin, 33, thatextends thro both legs of the bar and also throught e support. The upper end'of each link bar is provided with-a head, 34, having a central vertical and threaded ope therein through which a set bolt, 35, extends all-for a purpose presently to be explained. The

upper sections of the shell are formed substantially like the lower sections so far as the slats or bars are concerned but these lat ter are not secured to brackets that are carried by the side walls but are partly circled at intervals by arched bars, 36, having squared shoulders, 37, at opposite sides, as

clearly seen in Fig. 6. These arched bars have the lateral flanges, 16, and semi-circular bars, 26, the same as described in connection with the lower bracket supports and the manner of securing the bars to the arched bars is precisely the same as in the lower sections. The upper sections however are provided at opposite sides with horizontal flanged bars, 38, which form the base of the upper arch and which fit in lower edge notches, 39, in the said arched bars to which they are secured by suitable fastenings, 40, as seen in broken lines in Fig. 7 The upper sections are seated on top of the lower bracket supports, '13, and the bifurcated link bars, 32, are swung over the shoulders, 37, of the arched bars and the set bolts, 35, are screwed down on said shoulders to rigidly hold the upper sections down on the lower.

bracket supports. In order to facilitate the operation of the link bars and permit ready access to the upper ends of said bars, I have provided a drop or depression, 41, in the upper edge of the side walls as clearly seen in Fig. 1. p

From the foregoing explanation it is to be understood that the spirally-threaded conveyer is inclosed from end to end by the upper and lower slatted sections which taper so as to conform to and snugly surround the screw,the slats or bars being spaced slightly at their inner surfaces which spaces increase in width from the inner toward the outer surfaces. 'A suitable slatted hopper, 42, is provided at the large end of the casing or shell through which the materials to be treated by the machine are' fed to the interior of the casing where the screw advances or forces it toward the smallerdischarge end. At the smaller end of the screw the machine is provided with acircular plate, 43, having an opening, 44, through which the screw shaft, 6, extends and the material forced from the smallest shell section, 31, passes through the'opening, 44, in said plate. over the discharge outlet, 45.

- up the machine at the outlet. To overcome.

this I provide a cutter, 46, in front of the outlet, 44,-so that the material will be forced against said cutter and sufiiciently divided to cause it to break loose from the shaft 6, and drop. In the resent instance the cutter is secured about t e shaft, 6, by means of a clamp, 47, and both cutters and clamp turn with said shaft. To drive the screw I provide a large gear, 48, on the end of the shaft,

, 6, beyond the bearing, 5, which gear meshes with and is driven by a pinion, 49, in a horizontal shaft, 50, that is sustained in suitable bearings above the sidewalls of the machine. A comparatively large gear, 51,

. is also carried on the shaft, 50, which meshes with and is driven by a pinion, 52, on another horizontal shaft, 53. driving pulley, 54, is also carried on this-latter shaft which in shown. It is believed to be obvious that the mapractice is driven by a belt, not

terials in traveling through the tapered cas- 'mg or shell will be more and more com- I pressed and any fluids such as water and oils -w1ll be pressed out and flow through the lon 'tudlnal she where t ey will be caught and conveyed off for further treatment. The longitudinal grooves being wider at discharge side than at-their inner sides will not become clogged because the small particles of materials that will pass into-the grooves will readily pass out.

Having thus described my invention what I claim and desirev to secure by Letters Patent is,
